Validate TOTP token (without creating a credential)
## TOTP Validation with Function Node
This template allows you to verify if a 6-digit TOTP code is valid using the corresponding TOTP secret. It can be used in an authentication system.
The inputs need to be:
- a base32 totp secret (String)
- a 6 digits code (String)
++Important:++ The 6-digit code must be in text format. If the code starts with zeros and is treated as a number, it could cause validation issues.
The function node will generate a 6-digit code from the TOTP secret, then compare it with the provided code. If they match, it will return `1` otherwise, it will return `0`.
## Example usage:
- You retrieve the user's TOTP secret from a database, then you want to verify if the 2FA code provided by the user is valid.
## Setup Guidelines
You only need the ==`TOTP VALIDATION`== node.
==You will need to modify lines `39` and `40`== of the node with the correct values for your specific context.
## Testing the Template
You can define a sample secret and code in the `EXAMPLE FIELDS` node of the template, then click `"Test Workflow"`.
If the code is valid for the provided secret, the flow will proceed to the `true` branch of the `IF CODE IS VALID` node. Otherwise, it will go to the `false` branch.
